What happens if theres not enough air space?

Question

So I want to have 2 12's. I can make a box about 1.3 cu. ft. but the subs are recommended to have .95 cu ft each. They will be getting .65 each and not .95 each. Thats 22% less air space than is recommended. How do you think the sound will be affected? Ive also heard that I can use polyfill to "trick it" into thinking it has more space. Thoughts on that too?

Answer 1

Are you building a ported or a sealed box? A ported box would not be effected as much because it is always getting a fresh supply of air via the port. With a sealed container you would probably loose a little in the sq department. A lower db would probably be achieved also. As far as the polyfill goes I have personally had no luck with this and can not tell a difference with or without.

Answer 2

if you build this the way you want make it ported it will sound louder as in the bass will hit harder. but the other difference is if you make this a sealed you may heat the woofers more causing them to wear and tear faster.

Answer 3

if it isn't enough air space ur speakers are not hitting at it 's potential and it also depends on if it is ported or sealed...if sealed u would be able to pick up the low bass easily and ported would hit harder cause of the air vented...but 22 percent isn't as bad as u think
